Sleep problems are common among adults with ADHD, but difficulty sleeping can have several causes. Racing thoughts, an irregular schedule, medication effects, anxiety, and separate sleep disorders may all need consideration. A steady routine or background sound may help some people; neither is a universal treatment for insomnia.
At night, the room may become quiet while your thoughts become more noticeable. You remember an unanswered message, plan tomorrow, revisit a conversation, and suddenly want to investigate a question that did not matter ten minutes ago.
The task appears simple, go to sleep, but sleep cannot be produced on command by trying harder.
First identify what “I cannot sleep” means
- Do you struggle to stop an activity and get into bed?
- Do you get into bed but remain awake?
- Do you wake repeatedly?
- Do you sleep long enough but still feel unrefreshed?
These problems can overlap, but they are not identical. A bedtime reminder may help with a delayed transition and do little for repeated awakenings. A more comfortable room will not necessarily solve worry about an unresolved problem.
The NIMH adult ADHD guide1 identifies sleep problems as common. It does not mean every sleep complaint should be attributed to ADHD without further assessment.
Make bedtime a transition
“Be asleep by eleven” specifies an outcome you cannot directly control. A wind-down routine identifies actions that are more under your control.
For example, choose a point to stop demanding activities, prepare what you need for the morning, and put unfinished intentions somewhere you can return to them. A short note saying “Ask about the invoice tomorrow” may remove the need to keep rehearsing it tonight.
These are practical options, not a prescribed insomnia programme. Keep the sequence brief enough to use when tired. An elaborate routine with many required steps can become another reason to postpone bed.
If a late-night task is genuinely urgent, deal with that reality. Otherwise, give it a place and a return time rather than turning the bed into a second office.
Can white noise help?
A steady sound may make unpredictable background noises less noticeable. Some people find that useful; others find the added sound irritating or stimulating.
It is important to separate this personal experience from research on attention. A 2024 systematic review and meta-analysis2 found a small average benefit of white or pink noise on laboratory task performance among children and college-age young adults with ADHD or elevated symptoms. It included 13 studies with 335 participants in those groups. It did not establish a treatment for adult insomnia, and it identified no brown-noise studies meeting its criteria.
If you try sound, keep it comfortably quiet and stop if it disrupts your rest. More volume does not mean more benefit. Avoid turning a sleep experiment into an endless search for the perfect playlist.
What about music for concentration during the day?
The same separation applies. A track that feels pleasant is not automatically improving the work. Noise evidence cannot be transferred wholesale to music, specific frequencies, or a branded ADHD playlist.
Try a small comparison using similar tasks. Notice whether you complete the work more accurately or with fewer interruptions, as well as whether you enjoy the sound. If choosing music consumes the work session, the setup has become part of the distraction.
You do not need to justify a helpful preference with a claim that it is changing your dopamine.
Keep a short record before changing everything
For a week or two, note approximate bedtimes, wake times, time spent awake, daytime sleepiness, and relevant changes in caffeine, alcohol, medication, or routine. This can make a conversation with a clinician more concrete.
Discuss persistent problems, especially if they affect daytime functioning. Mention loud snoring, gasping during sleep, or marked sleepiness rather than assuming they are part of ADHD. Medication timing and effects should be reviewed with the prescriber, not adjusted by following somebody else’s schedule.
For long-term insomnia, NHLBI guidance describes cognitive behavioural therapy for insomnia, or CBT-I, as a usual first treatment option3. It is a structured treatment, not merely a list of sleep-hygiene tips.
A useful next step is to identify the sleep problem you actually have. The answer may involve routines, treatment, or both. It rarely begins with telling yourself to concentrate harder on being unconscious.
